Next, a manufacturing method of the engaging Rukin genus labels and Metals plate to the invention, by way of preferred embodiments will be described below with reference to the accompanying drawings. In the embodiment, description will be made by taking as an example a metal label used for product management of a steel piece by describing required information as a metal plate (sheet-like material) and sticking it to the end face of the steel piece. The metal labels are formed in the same shape, and are held in the supply unit of the label sticking device in a state of being stacked in alignment with each other. In this state, the metal labels are taken out one by one from the uppermost stage, and the next process ( Label affixing step). Here, the transfer means employs a means for adsorbing and holding the central portion of the metal label using the negative suction pressure of air. In addition, the front-back direction said in an Example is designated on the basis of the supply direction of the metal sheet with respect to a press die.

  As shown in FIG. 1, a metal label 10 according to an embodiment has a substantially rectangular thin metal plate as a metal plate main body (hereinafter abbreviated as a main body) 12, and one surface of the main body 12 (the surface of the metal label 10). 10a is coated with a coating material, and a base 14 for printing information such as an identification symbol is laminated. The base 14 is formed in a band shape across the other opposing edge in the central region excluding the vicinity of one opposing edge in the main body 12, and is set to a thickness of about 20 μm in the embodiment. Then, the metal label 10 is transferred in a state where the surface 10a provided with the base 14 is held by the transfer means 22 (see FIG. 2), and the back surface 10b is brought into contact with the end surface of the steel piece so It is fixed to the steel slab by spot welding the four corners with the welding electrode. That is, in the metal label 10, the base body 14 is not applied to the main body 12, and spot welding is performed on the end face of the steel slab in a region 16 (plain region) where the surface of the main body 12 is exposed.

  The metal label 10 has a plurality of (four in the embodiment) convex portions on the plain region 16 which is the peripheral portion of the main body 12 where necessary information is written and the base 14 held by the transfer means 22 is avoided. 18 is provided. In addition, the plurality of convex portions 18 are arranged so as to avoid a portion where the welding electrode comes into contact when spot welding to the steel piece in the metal label 10. Each protrusion 18 is formed to protrude from the back surface 10b of the metal label 10 and is set to be larger than the thickness of the base layer 14 so as to protrude from the main body 12 by about 0.1 mm, for example. That is, when the metal labels 10 are stacked on each other, the front end surfaces of the convex portions 18 come into contact with the surface (facing surfaces) 10a of the metal label 10 located on the lower stage, so that the upper and lower metal labels 10, 10 It is comprised so that a clearance gap may be defined between opposing surfaces (refer FIG. 2).

  The convex portions 18 of the embodiment are portions formed by plastic deformation of the main body 12 itself by stamping with a punch 36, which will be described later, and projecting in shape, and the surface 10a of the metal label 10 corresponds to each convex portion 18. Thus, the recesses 20 are respectively recessed. The plurality of convex portions 18 are arranged in an asymmetric relationship across one center line (first center line: left-right direction in FIG. 1) L1 in the main body 12, and the other center orthogonal to the first center line L1. Lines (second center line: up and down direction in FIG. 1) L2 are arranged in a symmetrical relationship across L2. In the embodiment, as shown in FIG. 1, in each plain region 16 extending in the left-right direction on the upper edge (one edge) and the lower edge (other edge) which is the opposite side, a set of convexes spaced apart in the left-right direction. The portions 18 and 18 are provided, respectively, and the separation width of the projections 18 and 18 of the lower edge set is set narrower than the separation width of the projections 18 and 18 of the upper edge set. Further, in the metal label 10, the protrusions 18 provided in the left half region and the right half region, respectively, are arranged in a straight line in the left-right direction at symmetrical positions with respect to the second center line L2 extending in the vertical direction. ing.

  In this way, when the metal labels 10 are stacked on each other with a simple configuration in which only the convex portions 18 are provided on the metal label 10, a gap can be defined between the upper and lower metal labels 10, 10. It can avoid that the opposing surfaces 10a and 10b of the metal labels 10 and 10 contact each other as a whole. That is, since a gap is defined between the opposing surfaces 10a and 10b of the metal label 10, a vacuum state does not occur like a suction cup, and adhesion between the metal labels 10 and 10 can be suppressed, and the upper metal label 10 by the transfer means 22 can be suppressed. As a result, the lower metal label 10 is not attached and supplied. Therefore, the metal labels 10 can be reliably supplied one by one from the stacked state to the next pasting process by the transfer means 22, so that the metal label 10 is not welded to the end face of the slab or the wrong metal label 10 Inconvenience such as sticking does not occur, and product management in the subsequent process can be performed smoothly.

  In the metal label 10, the plurality of convex portions 18 are arranged in an asymmetric relationship across the first center line L <b> 1 of the main body 12, so that the metal labels 10 having the same planar shape are alternately stacked in the upper and lower stages. Thus, it can be avoided that the concave portion 20 of the metal label 10 located in the lower stage and the convex portion 18 of the metal label 10 located in the upper stage are aligned (see FIG. 3 or FIG. 4). Therefore, even if the convex portion 18 is formed on the metal label 10 by punching with the punch 36, the convex portion 18 and the concave portion 20 are not fitted when the metal label 10 is stacked, and the metal label 10 is taken out. Can be performed smoothly one by one.

  As shown in FIG. The metal label 10 is manufactured by punching from a long metal sheet S by a press device including a press die 30 including an upper die 32 that is a male die and a lower die 38 that is a female die corresponding thereto. . The upper die 32 punches the rear half body 12b of the metal label 10 and separates it from the metal sheet S, and punches the front half body 12a of the next metal label 10 in the metal sheet S and protrudes in a substantially H shape in plan view. The portion 34 and the punch 36 for engraving the convex portion 18 are provided, and are configured to move forward and backward with respect to the lower die 38 by driving means (not shown). The lower die 38 includes a groove portion 40 corresponding to the punch portion 34 of the upper die and a punch groove 42 disposed corresponding to each punch 36 and forming the outer shape of the convex portion 18. The punch 36 is disposed in an asymmetrical relationship across the supply direction (parallel to the first center line L1) of the metal sheet S in the upper die 32, and the separation line (second center line) of the metal label 10 from the metal sheet S. They are arranged in a symmetrical relationship with respect to the line L2. In addition, as an example of the press die 30 of the embodiment, a configuration in which the upper die 32 moves forward and backward with respect to the lower die 38 has been described as an example. However, even when the lower die is driven, both the upper die and the lower die are driven. May be. 5 shows a state in which the upper die 32 is opened so as to be orthogonal to the lower die 38 for the convenience of explanation (see FIG. 5A). And the groove portion 40 are vertically moved opposite to each other.

  A method for manufacturing the metal label 10 according to the embodiment using the press apparatus including the press die 30 configured as described above will be described. The metal sheet S drawn out from the coil is sequentially supplied to the press die 30 (see FIG. 5A). The metal sheet S is preliminarily coated with a coating as a base 14 in a strip shape in a direction along the long side. By moving the upper die 32 toward the lower die 38, the second half 12b of the metal label 10 in which the front half 12a is punched and formed by the previous pressing process in the front region of the press die 30 is formed by punching from the metal sheet S. (See FIG. 5 (b)). Further, in the rear region of the press die 30, a portion that becomes the front half body 12 a of the next metal label 10 is punched out from the metal sheet S. Further, simultaneously with the punching of the outer shape of the metal label 10, the convex portion 18 is stamped by the punch 36, so that the plain regions 16, extending across the base 14 in the halves 12 a, 12 b of the metal label 10, 16, convex portions 18 are formed at positions shifted from each other. The upper die 32 is separated from the lower die 38, the metal label 10 is taken out, and the metal sheet S is sent forward in the supply direction (see FIG. 5C). By repeating these steps, metal labels 10 having the same shape are sequentially formed. Then, the metal label 10 obtained by the pressing device is held in a state where the metal label 10 is inverted by 180 ° in a plan view and alternately stacked in the supply unit of the label sticking device, and is prepared for removal by the transfer means 22.

  According to the method of manufacturing the metal label 10 using the press die 30 described above, in one press process, the formation of the portion to be the latter half 12b of the metal label 10 in which the first half 12a is formed in the previous press process and the metal sheet S. One metal label 10 to be separated from the other, the formation of the front half body 12a in the next metal label 10, and the formation of the convex portion 18 in the metal label 10 can be performed simultaneously, and the production efficiency is excellent.
